Description

Technical Field

[0001] This utility model relates to the field of sealing cap technology, and in particular to a rust-preventive oil filling and anti-oxidation sealing device. Background Technology

[0002] Rust-preventive oil is a reddish-brown oil-based solvent with rust-preventing properties. It consists of oil-soluble corrosion inhibitors, base oils, and auxiliary additives. Based on performance and application, rust-preventive oils can be categorized into fingerprint-removing rust-preventive oils, water-dilutable rust-preventive oils, solvent-dilutable rust-preventive oils, dual-purpose rust-preventive and lubricating oils, storage rust-preventive oils, displacement rust-preventive oils, thin-film oils, rust-preventive greases, and vapor-phase rust-preventive oils, among others.

[0003] In the existing technology, rust-preventive oil will oxidize after prolonged contact with air. Therefore, the can needs to be sealed in time after filling. The current sealing method is to directly seal it with a cap. In order to ensure the sealing effect, the cap is connected to the can opening quite tightly. However, with this method, it is difficult to remove the cap when the rust-preventive oil needs to be taken out, which is inconvenient. Utility Model Content

[0004] The purpose of this invention is to solve the problem that rust-preventive oil oxidizes after prolonged contact with air in the existing technology. Therefore, the can needs to be sealed in time after filling. The current sealing method is to directly seal it with a cap. In order to ensure the sealing effect, the cap is connected to the can opening tightly. However, this method makes it difficult to remove the cap when the rust-preventive oil needs to be taken out, which is inconvenient. Therefore, this invention proposes a rust-preventive oil filling and anti-oxidation sealing device.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a rust-preventive oil filling and anti-oxidation sealing device, comprising a sealing cap, a friction-increasing protrusion fixedly connected to the outer surface of the sealing cap, a fastening bolt provided on the inner wall of the sealing cap, an inner sleeve fixedly connected to the upper end of the inner part of the sealing cap, a sealing ring provided between the inner sleeve and the sealing cap, a threaded sleeve fixedly connected to the upper end of the sealing cap, a clamping bolt connected to the inner thread of the threaded sleeve, and a sealing pressure frame provided between the inner sleeve and the sealing cap and above the sealing ring, the lower end of the sealing pressure frame being a circular ring design.

[0006] Preferably, the sealing cap has a fixed air extraction port in the middle, and a sealing platform is fixedly connected to the lower middle part of the air extraction port. An assembly bottom groove is opened at the lower end of the sealing platform, and a permanent magnet is fixedly connected inside the assembly bottom groove.

[0007] Preferably, the inner ring surface of the sealing platform is an inclined surface, and a sealing gasket is fixedly connected to the inclined surface.

[0008] Preferably, the upper part of the center of the air extraction port is threaded, and a threaded bracket is threadedly connected to the upper part of the center of the air extraction port. The lower end of the threaded bracket is fixedly connected to a bottom insertion tube.

[0009] Preferably, a pressing block is provided below the bottom insertion tube, and an assembly end groove is provided at the upper end of the pressing block, with a metal ring fixedly connected inside the assembly end groove.

[0010] Preferably, the upper end of the pressing block is provided with an inner slot, and a pull rod is fixedly connected inside the inner slot.

[0011] Preferably, the pull rod passes through the bottom insertion tube, and the bottom insertion tube is inserted into the inner slot.

[0012] Compared with the prior art, the advantages and positive effects of this utility model are as follows: 1. In this utility model, by setting up the clamping bolt and the sealing pressure frame, when connecting the sealing cover to the rust-preventive oil storage tank, after the clamping bolt is screwed to the top, the lower end of the sealing ring can be squeezed. By rotating the clamping bolt, the sealing pressure frame moves down, which can press down on the upper end of the sealing ring, thereby deforming both the upper and lower ends of the sealing ring and improving the sealing effect. Moreover, the structure is relatively simple. When disassembling, the clamping bolt can be removed with an electric wrench, and the sealing cover can be removed with a small force, making disassembly and assembly convenient and quick. In addition, this design can make the pressure different at different points on the upper end of the sealing ring, so that the sealing ring is tilted, which can be used for installation on tank openings with uneven end faces, and has a wide range of applications.

[0013] 2. In this utility model, the air extraction port is designed to connect with an air pump or vacuum pump to extract the gas from the rust-preventive oil storage tank, thereby preventing the rust-preventive oil from contacting the air. At the same time, the permanent magnet and metal ring design allows the lower pressure block to move down quickly, ensuring a sealing effect. The sealing gasket further guarantees the sealing performance. The threaded bracket design restricts the position of the lower pressure block, preventing it from detaching during air extraction and facilitating disassembly. It is also simple to use. The bottom insertion tube design restricts the direction of movement of the lower pressure block, preventing it from deviating. Attached Figure Description

[0016] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0017] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0018] Example 1: As Figure 1 - Figure 4 As shown, this utility model provides a rust-preventive oil filling and anti-oxidation sealing device, including a sealing cap 1. The outer surface of the sealing cap 1 is fixedly connected with friction-increasing protrusions 2. The inner wall of the sealing cap 1 is provided with fastening bolts 7. The upper end of the inner part of the sealing cap 1 is fixedly connected with an inner sleeve 8. A sealing ring 13 is provided between the inner sleeve 8 and the sealing cap 1. The upper end of the sealing cap 1 is fixedly connected with a threaded sleeve 4. The inner thread of the threaded sleeve 4 is connected with a clamping bolt 5. A sealing pressure frame 11 is provided between the inner sleeve 8 and the sealing cap 1 and above the sealing ring 13. The lower end of the sealing pressure frame 11 is a circular ring design.

[0019] The specific settings and functions of this embodiment are described in detail below. By setting the clamping bolt 5 and the sealing pressure bracket 11, when connecting the sealing cover 1 to the rust-preventive oil storage tank, after the fastening bolt 7 is screwed to the top, the lower end of the sealing ring 13 can be squeezed. By rotating the clamping bolt 5, the sealing pressure bracket 11 is moved down, which can press down the upper end face of the sealing ring 13, thereby deforming both the upper and lower ends of the sealing ring 13, improving the sealing effect. Moreover, the structure is relatively simple. When disassembling, the clamping bolt 5 can be removed with an electric wrench, and the sealing cover 1 can be removed with a small force, making disassembly and assembly convenient and quick. In addition, this design can make the pressure different at different points on the upper end of the sealing ring 13, causing the sealing ring 13 to tilt, which can be used for installation on tank openings with uneven end faces, and has a wide range of applications.

[0020] Example 2: As shown in the figure - Figure 5 As shown, the sealing cap 1 has a fixed connection to the air extraction port 3 in the middle. The lower part of the middle of the air extraction port 3 is fixedly connected to the sealing platform 10. The lower end of the sealing platform 10 has an assembly bottom groove 12. The interior of the assembly bottom groove 12 is fixedly connected to the permanent magnet 9. The inner ring surface of the sealing platform 10 is inclined, and the inclined surface is fixedly connected to the fitting sealing gasket 14. The upper part of the middle of the air extraction port 3 has a threaded design. The upper part of the middle of the air extraction port 3 is threadedly connected to the threaded bracket 18. The lower end of the threaded bracket 18 is fixedly connected to the bottom insertion tube 19. The lower part of the bottom insertion tube 19 is provided with a lower pressure block 15. The upper end of the lower pressure block 15 has an assembly end groove 16. The interior of the assembly end groove 16 is fixedly connected to the metal ring 17. The upper end of the lower pressure block 15 has an inner slot 20. The interior of the inner slot 20 is fixedly connected to the pull rod 6. The pull rod 6 passes through the bottom insertion tube 19, and the bottom insertion tube 19 is inserted into the inner slot 20.

[0021] The overall effect of this embodiment is that, through the setting of the air extraction port 3, it is used to connect with an air extraction pump or a vacuum pump to extract the gas in the rust-preventive oil storage tank, thereby preventing the rust-preventive oil from contacting the air. At the same time, through the setting of the permanent magnet 9 and the metal ring 17, the lower pressure block 15 moves down quickly to ensure the sealing effect. The sealing gasket 14 further ensures the sealing performance. The setting of the threaded bracket 18 is used to restrict the position of the lower pressure block 15 to prevent the lower pressure block 15 from falling off during air extraction. It is also easy to disassemble and use. The setting of the bottom insertion tube 19 is used to restrict the movement direction of the lower pressure block 15 to prevent deviation.

[0022] The usage and working principle of this device are as follows: During installation, connect the fastening bolt 7 to the opening of the rust-preventive oil storage tank. When screwed to the top, the upper end of the tank opening contacts the lower end face of the sealing ring 13. Then, connect the clamping bolt 5 to the threaded sleeve 4 to press the sealing pressure frame 11, causing the sealing pressure frame 11 to move downward and press the sealing ring 13, thereby deforming the sealing ring 13 and sealing it. Then, connect the vacuum pump to the air extraction port 3 to extract the air from the rust-preventive oil storage tank, making it a vacuum. After the air extraction is completed, the metal ring 17 is attracted by the magnetic force of the permanent magnet 9, causing the lower pressure block 15 to move downward and contact the sealing gasket 14, sealing the air extraction port 3. When the vacuum pump is disconnected, because the pressure inside the rust-preventive oil storage tank is low and the external pressure is high, the lower pressure block 15 will be squeezed, causing the sealing gasket 14 to be squeezed and deformed, thus ensuring the sealing effect.

[0023] The above are merely preferred embodiments of this utility model and are not intended to limit the utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of this utility model without departing from the technical solution of this utility model shall still fall within the protection scope of this utility model.
